Suddenly, a tiny yet beautiful fairy appeared on their table and said, "For being such an exemplary married couple and for being faithful to each other for all this time, I will grant you each a wish. "Ooh, I want to travel around the world with my darling husband." said the wife.
The fairy moved her magic stick and - abracadabra! - two tickets for the new QM2 luxury liner appeared in her hands.
Now it was the husbands turn. He thought for a moment and said: "Well this is all very romantic, but an opportunity like this only occurs once in a lifetime, so, I'm sorry my love, but my wish is to have a wife 30 years younger than me."
The wife, and the fairy, were deeply disappointed, but a wish is a wish... So the fairy made a circle with her magic stick and -abracadabra! - the husband became 92 years old.
The moral of this story: "Fairies are female."
